"Jose and his team were extremely professional, highly knowledgeable, and incredibly helpful throughout the entire project. He provided a fair price without compromising on quality, and his attention to detail was amazing. The final result came out even better than I expected! One of the things I appreciated most was how clean and organized they were. They always kept the work area neat, taking extra care to minimize dust and prevent it from spreading to other parts of the house. I would absolutely hire him again and highly recommend Jose to anyone looking for a skilled, reliable, and detail-oriented contractor. A true professional!"

"I have never had the experience of remodeling a kitchen; and from what I had heard from people who did a remodel; it was a horrendous experience. I can truly say Homecraft(Norman) advised me through the entire process and I have nothing but positive feedback to give anyone who asks me. Norman’s staff of electricians and Dal his contractor were quite talented and professional. Overall I would highly recommend Homecraft for any remodeling project."

"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

"

This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.







Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. 

Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. 

This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.

I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

Unfinished Carpentry FAQs, answered by experts

No rules state how much of a load-bearing wall can be removed. Rather, you need to adequately support any area that is removed. Support should always be added to as much wall area is being removed. Failing to support the area properly will result in structural damage.

There are a few easy ways to locate a wall stud without a stud finder. First, try knocking on the wall with your knuckles. Most parts of the wall will sound hollow, but when you tap over a stud, it will sound more solid. Alternatively, since studs are spaced 16 or 24 inches apart, you can measure those distances from a corner of the room, which will always have a stud.

Most of the time, you’ll want to use screws on your subfloor rather than nails. Nails can actually weaken plywood, whereas screws can easily penetrate without damage. They also form a more secure connection because of their shape, preventing squeaky floors and tightly holding the subfloor in place. That said, some contractors do prefer nails depending on the type of floor covering because they allow for more flexibility.

Installing a tongue-and-groove wall requires similar techniques to those associated with installing shiplap. However, because of the precision necessary to make each board fit perfectly and the increased material prices, the cost is higher than that of shiplap installations. Expect to spend between $2 and $6 more per square foot for tongue-and-groove walls versus shiplap ones.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.
